@uitrit tets a'trnt @frn JAMES N. FREESTONE, OF WILLIAMSBURG, NEW. YORK.
Letters Patent No. 68,431, dated September 3, 1867.
IMPROVBD WRENCH.
@te .gagnait referto la in tiges tettcrs ntent inn uniting part nf tigt sinus.
TO ALL WHOM IT MAY GONCERN:
Beit known that I, JAMES N. FREESTONE, of Williamsburg, Kings county, and State of New York, have invented a new and improved Pipe-Wrench; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of my invention consists in providing the sliding-piece (which in ordinary wrenches forms the lower jaw) with fulcrunhpins, to which I connect an independent movable angular-shaped claw; this claw forms the upper jaw of the wrench. The lower or Acorresponding jaw I form at the upper end of the wrench' handle; the object ofthe whole combination being to secure airmer grasp in holding either a pipe or abolt, Ste.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
Figure 1 represents a side view of the wrench. f
Figure 2 is a front view of tho same.
Figure S-is also a side View and section of sliding-piece.
The sliding-piece S which usually forms the lower jaw of an adjustable wrench is provided with two fulcrum-pins,pp, situate one on each side of said sliding-piece S. Connected to the fulerum-pins p p is a movable angular-shaped claw, C; this claw forms the upper jaw of the wrench. The lower jaw e is formed bythe peculiar tooth-shaped upper end of the wrench-handle H. This handle is made to pass through the mortise within the sliding-piece S. This handle has a toothed rack, 1', which gears into one or more teeth, o, contained within the mortise ofthe sliding-piece S, for the purpose of adjusting the distance between the upper and lower jaw. A spring, x, is firmly secured to the back of the sliding-piece S, which causes the claw C to keep its proper position. Now, by grasping a pipe, .a bolt, or their equivalent, within the jaws of the wrench,
and drawing the handle H in the proper direction, the teeth of the rack Twill engage the tooth or teeth o of the' sliding-piece S, and the fulcrum-pinspp are made to describe a circle, whose centre lies within a point of the lower jaw c; this causes the upper jaw C to move towards the lower or corresponding jaw e. The motion of the wrench-handle H tightens the grasp, and renders the wrench most e'licient for its purpose.
Claim.
What I claim as my invention, and desire to secure by Letters Patent, is The sliding-piece S, with its tooth O, handle H,jaw C, and spring X, all constructed and arranged to .operate substantially as described.
JAMES N. FREES'IONE.
